vesicoureteral reflux

vesicoureteral reflux The abnormal back flow of urine from the bladder into the ureters toward the kidneys. Abbreviated VUR. VUR is most commonly diagnosed during infancy and childhood and can be due to a congenital dysfunction in the valve where the ureter enters the bladder or to an acquired blockage in the urinary tract. VUR does not cause any pain or symptoms directly but is often discovered because VUR leads to urinary tract infections (UTIs). Treatment can involve medications or surgery. If not monitored carefully, ongoing reflux and repeated UTIs can cause serious kidney injury and possibly kidney failure.
